IMPROVEMENT IN MACHINES FOR MAKING METALLIC SHOE-SHANKS.

Specification forming part of Letters Patent No. 1 50,760, dated May 12, 1874 application filed April 4, 1874.

To all whom it may concern: Be it known that I, JOHN HYSLOP, Jr., of Abington, in the county of Plymouth and State of Massachusetts, have invented a new and Improved Machine for Making Metallic Shoe-Shanks, of which the following is a specification My present invention consists of the movable die for cutting the shank 0d the metal strip and shaping the edges, contrived also in suitable form on the bottom end to form one of the dies for producing the middle bend, and also the reverse bend, and combined with a stationary counterpart die, so that the cutting, shaping, and bending may all be accomplished at one operation, thus considerably simplifying and cheapening the machine and facilitating the work. My invention also consists of a peculiar arrangement of dischargers in connection with the cuttin g-dies for throwing off the waste pieces. My invention also consists of a novel arrangement of dischargers, in combination with the stationary bendingdie, for throwing the completed shanks off from it.

Figure 1 is a back view of my improved machine. on the line no a: of Fig. 1. Fig. 3 is a horizontal section taken on the line 3 y of Fig. 1. Fig. 4 is a detail of the mechanism for operating the dischargers forthrowingoftthe wastepieces. Fig. 5 is a detail of the apparatus for throwin g off the finished shanks. Fig. 6 is a plan view, and Fig. 7 is a side elevation, of a shank.

Similar letters of reference indicate correspondin g parts.

A is the movable cutting-die, and B the stationary cutting-die, for cutting off the shanks from the strip of metal, and shaping the edges. These dies are the same as those used in other machines for making these shanks, so far as the cutting and shaping of the edges of the blanks-are concerned; but for bending the shanks also I propose to have a deep concave notch, G, and the reverse convex curves D in the lower end or bottom of the movable cutting-die; and below the stationary cutting'die I arrange a stationary bending-die, E, which is the counterpart of the bottom 0 D of the other, to receive the blank directly from the cutters, and to serve as an anvil for bending it, the die A being geared so as to strike with sufficient force on the blank to set it in the shape required. Thus I save the employment Fig. 2 is a sectional elevation taken of a special set of dies in this kind of machines for bending the shanks. F is the stop-gage for stopping the plate G at the required point when fed along after each blank is cut off. It is suspended from a swinging arm, H, on the cross-head I, which is held down on the stationary cutting die, when the plate is fed along, by a spring, J, but is lifted a little, immediately after the waste-piece is cut off, by striking 011 the stationary arm K, to allow the dischargers L to throw off the piece. These dischargers are connected to a rock-shaft, N, pivoted to the cross-head at M, and having an arm, 0, extending up to the cam P on the crankshaft Q, to be swung back into recesses R in the side of the die A, to pass down beyond the edge of the piece for throwing it off when the cam escapes from the end of arm .0, and the spring S causes it to fly back. T represents the dischargers for throwing oil the finished shanks from the anvil-die E. They are mounted on the cranked rock-shaft U,

which is connected by a rod, V, with the cam W on the crank-shaft, so that when the cam passes under the arm X, at the top of rod V,

the dischargers are swung back into recesses Y in the die, to receive the blank in front of them, so that when the cam lets the rod down again its weight throws the dischargers forward and they throw oft the shanks.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The movable die A for cutting oft the blanks and shaping the edges of shoeshanks, having the bottom shaped to produce the middle and reverse bends, and combined with a stationary counterpart bending die, E, substantially as specified.

2. The dischargers L for throwing 0d the waste pieces, rock-shaft N, arm 0, cam P, and spring S, combined with the dies A and B, the die A having recesses R for the dischargers to enter to pass below the pieces to be thrown off, substantially as specified.

3. The dischargers T, cranked rock-shaft U, rod V X, and cam W, on the driving-shaft, combined with the stationary die T having recesses Y, all substantially as specified.
